Though Roki Sasaki’s deal with the Dodgers wasn’t anywhere close to the winter’s biggest, few free agents were so coveted or came with as much hype attached. Known as “The LeBron James of Japanese baseball” for his exploits in high school, he was dominant — even transcendent — during his 2021–24 NPB run with the Chiba Lotte Marines. As he went through the posting process, his combination of youth and a tantalizing repertoire featuring an elite, 80-grade splitter as well as a fastball with triple-digit velocity generated widespread interest by teams, though a dip in that velo last year did rate as a cause for concern. Now, eight starts into his career with the Dodgers, the 23-year-old righty has been underwhelming, and now he’s hurt, too. On Tuesday, the team placed him on the 15-day injured list due to a shoulder impingement, continuing the dizzying level of turnover within the rotation of the NL West leaders.

This is the latest turn in what’s been a rocky rookie season for Roki. Through 34.1 innings — about 4 1/3 per start — he’s carrying a 4.72 ERA, a 6.16 FIP, and a 6.13 xERA. He’s struck out just 15.6% of batters, while walking 14.3% (the highest mark of any pitcher with at least 30 innings), and has served up 1.57 homers per nine. His 21.9% chase rate is the third-lowest at that 30-inning cutoff.

Batters have struggled to do anything with Sasaki’s splitter, which he’s thrown in the zone just 29.6% of the time; they’ve chased it 30.4% of the time, and overall have hit .137 and slugged .237 against it. Even so, his 35% whiff rate on the pitch is well off the 56.5% whiff rate it generated last year in NPB according to Sports Info Solutions. Batters have fared better against his slider (.250 AVG/.417 SLG, 33.3% whiff) and his four-seamer (.253 VG/.494 SLG, 10.1% whiff), rarely chasing either (14% of the time for the former, 15% for the latter). All six of his home runs allowed have been off of four-seamers, as have two would-be homers robbed by Andy Pages; his xSLG on that pitch is a worrisome .663. His 17.8% whiff rate on four-seamers in the upper third of the strike zone or higher is better, but batters have still slugged .692 on pitches there, with a .903 xSLG. Read the rest of this entry »

It’s been one week since the Pirates fired manager Derek Shelton and replaced him with former major league utilityman and Pittsburgh native Don Kelly, who served as Shelton’s bench coach for the entirety of his managerial stint. Firing the manager is one of the first moves made by an underperforming or flat-out awful ballclub, so there’s nothing surprising about Shelton getting the axe after a 12-26 start. But a manager’s record is only as good as the players on his roster and the money spent to build that roster, and Pittsburgh was deficient in both for Shelton’s entire tenure, which spanned five-plus seasons. During that time, the team posted a 308-441 record.

Now with Kelly at the helm, the Pirates are still on a ship that’s at best treading water; they are 3-3 in their six games since he took over, with five of them being decided by just one run. Perhaps Pittsburgh will be better with Kelly managing than it was under Shelton. After all, this is a team that at least has Paul Skenes and Oneil Cruz. However, there is only so much that Kelly can do here. The core problems in Pittsburgh can only be solved with a drastic shift in organizational philosophy, and that starts with owner Bob Nutting and the person tasked with executing that strategy, general manager Ben Cherington.

Below is an analysis of the prospects in the farm system of the Milwaukee Brewers. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Marcus Semien was a promising prospect heading into the 2013 season, but he was far from a high-profile player. When that year’s Baseball America Prospect Handbook was published, the 2011 sixth-round pick out of the University of California-Berkeley was ranked just 14th in a light Chicago White Sox system. (At the time, in-depth scouting reports were still in their nascent stages here at FanGraphs.)

In the 12 years since then, the 34-year-old Semien has gone on to exceed those modest expectations. He reached the big leagues with the White Sox in September 2013, then established himself as an everyday player after they traded him to the Athletics before the 2015 season. Now in his fourth year with the Rangers after six seasons in Oakland and one in Toronto, the Bay Area native has three All-Star selections, two Silver Sluggers, and a Gold Glove on his résumé. Scuffling in the current campaign — Semien has a 47 wRC+ over 176 plate appearances — he nonetheless has 1,533 hits, including 241 home runs, to go with a 108 wRC+ and 36.1 WAR over his major league career.

What did Semien’s Baseball America scouting report look like in the spring of 2013? Moreover, what does he think about it all these years later? Wanting to find out, I shared some of what then-BA contributing writer Phil Rogers wrote, and asked Semien to respond to it.

———

“The son of former California wide receiver [Damien] Semien, Marcus was a three-sport standout in high school who followed his father’s footsteps to Berkeley, where he focused on baseball.”

“I actually just played basketball and baseball in high school,” Semien replied. “I was part of a state championship runner-up in my senior year, so I missed probably the first three weeks of my [baseball] season. Once I graduated high school, I knew that baseball was all that I was going to play in college.” Read the rest of this entry »

Rich Hill has a chance. On Tuesday, the Royals announced they had agreed to a minor league deal with the 45-year-old left-handed starter. He began his professional career in 2002 with the Boise Hawks, who are no longer part of affiliated baseball. Hill’s journey from the majors to independent ball, then back to a career renaissance in his late 30s is one of the game’s true feel-good stories, and it’s not over yet. If he makes it to Kansas City, he’ll tie Edwin Jackson as the most useful player on Immaculate Grid, with appearances for 14 different major league teams. However, that’s by no means a sure thing.

Hill started the 2015 season – yes, this historical overview section is skipping over the first 13 years of Hill’s professional career – with the Long Island Ducks of the Atlantic League. The Red Sox signed him that August, and from 2015 to 2020, he went 43-22 with a 2.92 ERA and 3.48 FIP. Over that stretch, relying (sometimes exclusively) on a four-seamer that averaged under 90 mph and a loopy curveball, Hill put up 10.7 WAR, struck out nearly 29% of the batters he faced, and pitched in two World Series to a 1.80 ERA.

The 2021 season, when Hill was 41, marks a dividing line. Over the past four seasons, he owns a 4.51 ERA with a 4.42 FIP and a 4.52 xFIP. His strikeout rate has fallen to 21.1%. In 2023, Hill posted a 4.76 ERA with the Pirates, then imploded after being traded to the Padres at the deadline, running an 8.23 ERA and 6.77 FIP over 10 appearances. He sat out the beginning of the 2024 season to spend time with his family, then joined the Red Sox in August, putting up a 4.91 ERA with ugly peripherals over four appearances and 3 2/3 innings. For the first time, his fastball didn’t reach 90 mph even once. The team released him in early September. Read the rest of this entry »

The world has changed in a lot of ways over the last dozen years, some good, and some… not. One thing that doesn’t change, however, is the status of Freddie Freeman at or near the top of the first base dogpile.

If at any point over the last decade you made a list of baseball’s top first basemen and didn’t include Freeman, you hopefully crumpled your list and started over again. Freeman will celebrate the 15th anniversary of his 2010 major league debut with the Braves later this year, and more than 2,000 hits and 350 homers later, he’s likely just rounding out the text on his bronze Hall of Fame plaque.

They say that the first step to fixing a problem is admitting that you have one. In that spirit, I’d like to start today’s article with a confession: I have a Trent Grisham evaluation problem. It feels good to say it! I’ve had this problem for years. Ever since he burst onto the scene in San Diego with two straight seasons of good hitting and great fielding, I’ve consistently overestimated his future trajectory. I put him on the first cut of my trade value list every year. I think of him as a starter even when the teams that employ him don’t.

I know all of this. When I’ve looked at Grisham in the past, I’ve seen an excellent player even when others haven’t, and I understand that this bias shades my evaluation. But just when I thought I was kicking the habit, Grisham goes and does something like this and pulls me right back in. Through Monday’s action, the first quarter of the season, he’s hitting a ludicrous .288/.373/.663, and while that’s not any reasonable hitter’s slugging percentage, he’s absolutely tattooing the ball, posting career high marks in barrel rate, hard-hit rate, xwOBACON, xSLG, average exit velocity… You get the idea, he’s just hitting everything very hard at the moment.

Now, as a reformed Grishamite, I have to tell you that hitting the ball hard isn’t one of Grisham’s shortcomings. Not quite like this, of course, because the only person who regularly hits like this is Aaron Judge, but he’s always been a threat to go deep. Grisham might have a low-ish wRC+ over the past three years, but the problem has been the quantity of his hits rather than the quality. Even while he scuffled mightily, he slugged roughly 20 homers per 600 plate appearances. He doesn’t always put the ball in play, but when he does, he makes it count.

Grisham also forces pitchers to come to him. He’s among the league’s best when it comes to chase rate, and he’s walking at a double digit clip. Again, though, I have to tell you that this isn’t new. Grisham’s chase rate is higher than it was last year, and his walk rate is below his career average. Unlike your typical outfielder with a below-average batting line, this isn’t an issue of Grisham never seeing a slider he doesn’t like. He’s quite willing to work a count if pitchers won’t challenge him in the zone. Read the rest of this entry »

Paul Molitor was a maestro with the bat. Over 21 seasons — 15 with the Milwaukee Brewers and three each with the Minnesota Twins and the Toronto Blue Jays — he recorded 3,319 hits, the 11th-highest total in major league history. Moreover, Molitor’s 605 doubles are tied for 15th most, while his 2,366 singles are 12th most. Walking nearly as often as he struck out (1,094 BB, 1,244 K) the sweet-swinging corner infielder/designated hitter put up a .306/.369/.448 slash line and a 122 wRC+.

Elected to the Hall of Fame in 2004, the St. Paul, Minnesota native went on to manage the Twins from 2015-2018, and prior to that he served as the team’s bench coach and as the hitting coach for the Seattle Mariners. Now an analyst on Twins radio broadcasts, Molitor sat down to talk hitting on a recent visit to Fenway Park.

David Laurila: You played [from 1978-1998]. Did hitters and/or hitting change over the course of your long career?

Paul Molitor: “I don’t think as drastically as we’ve seen over the past 10 years or so. I don’t know if we’ve ever been through a period where the percentage of teams’ runs scored were as closely related to how many home runs they hit. The game is always evolving. Breaking down the game in terms of what plays, the numbers show how driving the baseball, getting extra-base hits, [produces runs].

“I do like the old-school. Trying to get hits is still a good thing. You’re obviously going to have guys in your lineup who are more prone to striking out, but they’re going to get you that two- or three-run homer every now and then. And then you have the guys who create the flow on the bases. If you can run the bases, you give yourself more opportunities to get in scoring position. A perfect example would be the 2025 Red Sox. They put a lot of pressure on teams defensively. I think both can work.

“So yeah, there have been changes, but again, not too much when I played. Guys were always trying to figure out how to get better, but the involvement of analytics has changed some of the approach — everything from uppercut swings to how pitchers are throwing the baseball, spinning the baseball. It all plays a part in the counter strategy that hitters are trying to employ.”

Laurila: What about you, personally? Did you change much over the years? Read the rest of this entry »

The Boston Red Sox bandwagon was crowded beyond the capacity limit this offseason, as you’d expect for a team that added Alex Bregman and Garrett Crochet over the winter, and put two near-majors prospects in the top seven of the preseason Top 100. I confess I was a passenger on this bandwagon; it was incredibly sweaty and at least one stranger sat on my lap for a couple stops.

But for all that hype, a quarter of the way through the season the results have been a bit of a let down. Boston is right where it was last year: around .500. Disappointing as that may be, most of the individual performances by Red Sox players have been within the realm of expectation. Surely it’s a bummer that Jarren Duran and Walker Buehler have only been about average this year, for instance, but I don’t know that it’s a monumental shock in either case.

The one player whose numbers are really knocking me out of my chair right now is Tanner Houck. Read the rest of this entry »

You could be forgiven for not noticing Jonathan Aranda until now. The former Top 100 prospect spent the past three years bouncing back and forth between Triple-A Durham and Tampa Bay without ever making more than 143 major league plate appearances in a single season. He missed substantial time due to injuries last year, and the majority of his time in the majors took place in September, once the Rays — a team that doesn’t get a ton of mainstream attention even when they’re successful — were out of the running. This year, the lefty-swinging 26-year-old has taken over the long half of a first base platoon for the Rays, and so far he’s been hitting the stuffing out of the ball.

After a trio of recent three-hit games — May 4 against the Yankees, May 8 against the Phillies, and May 11 against the Brewers — Aranda is currently batting .342/.429/.553, good enough to place among the AL’s top six in all three slash-stat categories. He ranks second in OBP and wRC+ (184), behind only Aaron Judge. His average exit velocity, hard-hit rate, sweet spot rate, expected batting average, expected slugging percentage, and expected wOBA all rank in the 94th percentile or above. Right now, he looks like the Rays’ next All-Star, filling the void left by the trade of Isaac Paredes, their lone 2024 representative at the Midsummer Classic. Read the rest of this entry »
